    • The Effect of Grain Refiner on Aluminium Filtration 

      Bao, Sarina; Yang, Jiawei; Akhtar, Shahid; Tundal, Ulf; Tjøtta, Stig; Pettersen, Tanja; Li, Yanjun (The Minerals, Metals & Materials Series;2367-1181, Peer reviewed; Journal article, 2021)
      Grain refinement of aluminium and its alloys is a common industrial practice. Fine equiaxed, grain structure leads to improved castability, strength, machinability, formability, and good surface finish. Filtration is one ...

    • Effect of Inclusion and Filtration on Grain Refinement Efficiency of Aluminum Alloy 

      Yang, Jiawei; Xu, Yijiang; Bao, Sarina; Akhtar, Shahid; Tundal, Ulf; Tjøtta, Stig; Li, Yanjun (Peer reviewed; Journal article, 2022)
      It is well known that the filtration efficiency of ceramic foam filters (CFF) on aluminum melt can be significantly reduced by the addition of grain refiner particles under a high inclusion load. Also, it is usually ...

    • The Influences of Grain Refiner, Inclusion Level, and Filter Grade on the Filtration Performance of Aluminum Melt 

      Yang, Jiawei; Bao, Sarina; Akhtar, Shahid; Tundal, Ulf; Tjøtta, Stig; Li, Yanjun (Peer reviewed; Journal article, 2021)
      The addition of grain refiner particles in the aluminum melt is known to reduce the filtration efficiency of ceramic foam filter (CFF). In the present work, a systematic study on the influence of the addition level of ...
